Style.com junkies may notice a new category called Pre-Fall buzzing up in the fashion scene. The label's pretty self explanatory - a shipment of clothes that hits stores before Fall's big load. But the idea of a Pre-Fall show is a pretty new phenomenon, and one that does take a bit of exploring, so last night at the Michael Kors soiree, we asked Vogue's Valerie Boster to illuminate us. Here's what she said: "We're used to thinking of the fashion calendar as halved - there's Fall/Winter, and then there's Spring/Summer. But in the past two or three years, shoppers have been able to see what's on the runways as soon as it debuts, thanks to the Internet. By the time a Spring '08 dress hits stores, you'll already recognize it from the runway and maybe even from a few celebrities. Some shoppers love this, but others are impatient - they've already moved onto what's next. A Pre-Fall or a Resort collection can placate that sense in shoppers that they need something new. Also, since Pre-Fall and Resort are all about the shoppers, the lines are generally more accessible. They're more about what women can wear, not about pushing forward an idea or a silhouette. They're easier for most people to wear." In fact, the Zac Posen Pre-Fall dress at left looks very easy for us to wear - we'll be hunting it down at Barneys ASAP.
